Which of the following explains how the frequency of sound waves determines the movement of the basilar membrane? (1.0 points)
A)Higher-frequency waves move the region of the basilar membrane that is close to the base of the cochlea, whereas lower-frequency waves move the region that is near the tip of the cochlea.
B)Higher-frequency waves move the region of the basilar membrane that is near the tip of the cochlea, whereas lower-frequency waves move the region that is close to the base of the cochlea.
C)Higher-frequency waves move the region of the basilar membrane that is near the middle of the cochlea, whereas lower-frequency waves move the region near the base of the cochlea.
D)Higher-frequency waves move the region of the basilar membrane that is closer to the scala tympani, whereas lower-frequency waves move the region that is closer to the scala vestibuli.

every el niño cycle is different. every year.

step 1: initiation

initiation is the beginning of transcription. it occurs when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

step 2: elongation

elongation is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

step 3: termination

termination is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
